Portfolio

I'm putting together my portfolio on my website http://www.zanet.co.uk/#toWork but I cant decide if i should keep with the "cartoon like graphics to represent my work. it could look like all i do is design flat cartoon-like web sites.

So I would love a little feedback from you.
Do you think I should present my portfolio screenshots with a more corporate business like look?
How do you present your portfolio screenshots?

Thanks in advance.
